ならない欠点があった。For this reason, electrical wiring is required between the various input sensors in the engine room and the control device inside the vehicle, and between the control device and the various loads in the engine room, and the time and cost required for this wiring and the wiring space are problems. . Furthermore, in recent years, a large number of in-vehicle electronic devices have been installed in the same vehicle, so it has become difficult to secure a place to install a control device. Furthermore, the sensor installed in the engine room has its own complex electronic circuits, such as a boost sensor and air flow sensor, to prevent induction nozzles from occurring in the wiring above the fuel injection device. It may be necessary to install noise countermeasure circuits in both control circuits, or
Similarly, constant voltage circuits must be provided on both sides, which not only requires an extra circuit, but also has the disadvantage of having to manage the voltage accuracy of both the noise suppression circuit and the constant voltage circuit at the same time. Ta.

とを目的としている。This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by making the control device itself highly integrated and making it possible to install it in the engine room, it is possible to effectively wire it with various sensors. The purpose of the present invention is to provide an engine control device that can be more highly integrated and has improved reliability by cooling the control device using the intake air of 4 hours per hour.
以下この発明の一実施例を図について説明する。An embodiment of the present invention will be described below with reference to the drawings.

Additionally, the influence of induced noise can also be reduced. In addition, since the pressure sensor 8 that controls the basic fuel amount of the engine is also integrated with the control device 7 and housed in the same casing 9, the constant voltage power supply circuit required for the pressure sensor 8 can also be shared. There is no need to set one up. In addition, external wiring between the control device 7 and the pressure sensor 8, which has been required in the past, is not required, and since external nozzles and radio interference induced into external wiring can be prevented, a filter circuit can also be omitted. Furthermore, in the case of a conventional separate power supply,
Voltage accuracy management, which was previously required, only needs to be done on one side.

The injection position of this injector 5 is not particularly limited and may be set at any position, but the important difference from Fig. 1 is that a part of the intake air passes through the engine control device 7 while being cooled. - This is the point. Thereby, in addition to the heat dissipated from the casing, the control device 7 can be forcibly cooled down by the heat generated from the internal circuit through the passage of the intake air.
